Hummus does freeze very nicely. As others have mentioned, simply give it a stir when it thaws. As far as Tahini goes, it does not need refrigeration. Being of Lebanese descent, Tahini is a staple in my home and I have never had it go bad and I've kept it in the pantry for months at a time. The salsa would have been the more likely cause of the food sickness.

At this point I'm definitely leaning more toward the salsa. Time frame wise it makes more sense.

Woo Hoo! It wasn't the hummus. I ate it again yesterday and no ill effects what so ever. I'm going to freeze a bunch so I have it for later. I don't have a food processor so I did it in the blender. Too much work for it to be thrown out and too much work to do again. I really need a food processor.
